冲击载荷下剪切断裂研究

利用Hopkinson压杆技术对单边平行双裂纹试样倒向加载，在较大的加载率范围，对Ti6Al4V钛合金和40CrNiMoA两种材料的动态剪切断裂行为进行了研究．实验结果表明：存在两类韧性剪切断裂模式，即常规的韧性剪切型断裂和绝热剪切断裂．常规剪切型断裂模式的断裂韧性KⅡd随加载率的提高而增大，而绝热剪切型的断裂韧性KⅡd则随加载率的提高而减小，并且，当加载率增大至某一临界值时，常规的韧性剪切断裂模式将转变为绝热剪切断裂破坏模式．     

陶瓷材料的动态压缩测试

陶瓷材料是地面车辆和航空器防护装甲的重要组成材料。一直以来，陶瓷材料的高应变率压缩性能都受到众多研究者的密切关注。陶瓷材料的高应变率压缩性能是通过SHPB试验获得的。对于传统的SHPB试验，必须满足“一维应力假设”、“试样的轴向应力均匀假设”和“压杆弹性假设”，才可以得到有效的测试结果。而这些基本假设均受到陶瓷材料高强度、高弹性模量和高脆性的挑战。

工艺参数对铀表面铝镀层热应力分布影响

为了防止铀的腐蚀，采用在铀表面磁控溅射镀铝，但使用中发现铝镀层内产生了较大的应力，影响镀层结合强度及使用性能。通常认为，薄膜内的应力有热应力和生长应力两种。文中通过改变沉积温度、镀层厚度以及镀层力学性能分数，研究它们对镀层热应力分布的影响，从而为改善铀表面铝镀层内热应力分布提供理论依据。     

Formation Mechanism and Orderly Structures of an Iron Film System Deposited on Silicone Oil Surfaces

A new iron film system,deposited on silicone oil surfaces by vapour phase deposition method,has been fabricated and its formation mechanism as well as orderly structures has been studied,It is found that the formation mechanism of the films obeys a two-stage growth model,which is similar to that to the other metallic films on liquid substrates,Large and orderly structures are observed in the continuous iron films.The experiments show that the orderly spatial structures result from the local material gathering in these nearly free sustained films.     

SURFACE METALLIZATION OF CENOSPHERES AND PRECIPITATORS BY ELECTROLESS PLATING

This paper reports the use of a colloidal Pd^0 catalysis system to metallize the surface of precipitators separated from coal fly-ash, and metals such as Cu, Ni etc. are deposited on the precipitators surface. Alternatively, according to the characteristic surface of cenospheres, an Ag coating catalysis system is adopted to first deposit Ag on the cenospheres surface, followed, if necessary, by the deposition of other metals such as Cu, Ni, etc. on the Ag coating to produce monolayer and multilayer metal-coated cenospheres. The surface characteristics and the morphologies of the metal coatings are examined in detail with scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS) techniques. It can be shown that the quality of metal coatings derived from the Aa coatina catalysis system, is better than that of the colloidal Pd^0 catalysis system.
